Fireworks lists the Ember-1 serverless API at $3.00 input, $0.30 cached input, and $15.00 output per million tokens for `accounts/fireworks/models/ember-1`. The model page states a 1,040K-token context. Fewer generated reasoning tokens may lower total task cost, but the per-token rates match the Kimi K3 rates quoted in the launch post.
